David E. Comings, M.D., a physician-scientist and former head of medical genetics at City of Hope, is calling for active removal of atmospheric carbon dioxide in a new book that argues reducing emissions alone will not be enough to protect future generations.
Book stresses permanence of CO₂ and need for removal
In The Science of Global Warming: And Four Ways to Fix It, Comings frames the climate challenge around the long residence time of carbon dioxide in the atmosphere. The book cites research indicating that CO₂ can remain for as long as 1,000 years, meaning that halting emissions today would not immediately reverse warming trends caused by gases already in the air.
Comings, who led medical genetics at City of Hope for 37 years, combines what the release describes as scientific analysis with visual material — the book features more than 106 full‑color illustrations — and extensive references intended to make the science accessible to a broad readership.
“Net zero is not enough. We must remove the excess already there if we want to protect future generations.”
The work advances the argument that a comprehensive policy response should include not only mitigation of new emissions but also intentional strategies to extract already‑emitted CO₂ from the atmosphere. According to the book’s summary, Comings presents four evidence‑based approaches that address multiple climate risks, including measures to:
- increase the earth’s albedo (reflectivity),
- reverse ocean acidification,
- and remove carbon dioxide from the atmosphere.
The description of the book indicates the approaches are intended to be practical and grounded in existing scientific literature. It highlights accelerating climate trends and potentially dangerous feedback loops that, if unchecked, could intensify environmental damage.
Background and implications
Comings’ background as a medical geneticist is emphasized in the announcement, along with his lengthy tenure leading a medical genetics program. That professional history is presented as part of the book’s credibility, suggesting a scientific and evidence‑based approach rather than advocacy alone.
The framing of removal as a necessary complement to emission reductions intersects with ongoing policy and technological debates. Scientists and policymakers have increasingly discussed carbon removal in recent years — ranging from natural approaches such as reforestation and soil carbon sequestration to engineered solutions like direct air capture. Comings’ book, according to the publisher’s summary, seeks to bring these conversations to a broader public by explaining the science and outlining concrete options.
The book’s emphasis on ocean acidification points to co‑benefits of some removal strategies; reducing CO₂ concentrations affects both atmospheric temperatures and ocean chemistry, which has consequences for marine ecosystems. Increasing planetary albedo, another focus described in the release, carries its own set of scientific, ethical and geopolitical considerations that climate researchers continue to evaluate.
While the release highlights the book’s visual and reference material, it does not enumerate the full list of the four approaches in detail within the summary provided. Readers and policymakers interested in the evidence base and implementation pathways would need to consult the book for the complete set of proposals, underlying citations and any discussion of risks or tradeoffs associated with the strategies.
| Fact | Detail |
|---|---|
| Author background | Former Head of Medical Genetics, City of Hope (37 years) |
| CO₂ lifetime cited | Up to 1,000 years |
| Illustrations | More than 106 full‑color images |
The book adds to a growing body of literature urging more attention to carbon removal as a component of climate strategy. As debate continues over how to balance emissions reductions, technological innovation and ecosystem protection, contributions that synthesize scientific findings for policymakers and the public can shape both understanding and political priorities.
Comings’ book is being positioned as a call to broaden the policy toolkit: not to replace efforts that cut emissions, but to supplement them with active steps to reduce the excess greenhouse gases already warming the planet.
